Log:
MFC revision 1.140
Eliminate an unnecessary call to vm_page_busy().
MFC revision 1.141
Pass VM_ALLOC_NOBUSY to vm_page_grab() so that we don't have to call
vm_page_flag_clear(PG_BUSY). The object lock is held the entire time.
Thus, whether or not the PG_BUSY flag is set is invisible to others.
MFC revision 1.145
Acquire the source pmap's lock in pmap_copy().
